Local governments continue to stand up against President Donald Trump’s decision to withdraw from the Paris Climate Agreement.

Iowa City mayor Jim Throgmorton recently signed two letters stating the city’s intention to uphold the principles of the Paris Accord — one from the Global Covenant of Mayors for Climate & Energy, and the other by the Climate Mayors, which was signed by 292 other mayors in the U.S. The Johnson County Board of Supervisors passed a resolution stating a similar objective at their meeting last week.

“We hope other counties will sign on as well,” Mike Carberry, vice chair of the supervisors, said to The Daily Iowan. “Since the president and the country aren’t going to show leadership, then local governments have to do it — cities, counties, maybe even states.”

Earlier this month, Trump announced his intent to ditch the agreement between 195 countries to reduce emissions to keep global temperatures from rising more than 1.5 degrees Celsius from pre-industrial levels.

Both Iowa City and Johnson County have a reputation of being particularly progressive, especially in terms of environmental action. Johnson County has built several Leadership in Energy and Environmental Design-certified buildings, increased its dependence on solar power, and implemented recycling and waste reduction practices. Iowa City set a goal to reduce its greenhouse gas output by 80 percent by 2050, established a committee aimed at climate action, and improved access to recycling and composting.

“In terms of the U.S. as a whole does, does it matter what Iowa City does?” Throgmorton said to The Daily Iowan. “No, I don’t think it matters, but if you combine all these cities in the United States … that adds up. It feels very powerful to me to know that what we’re doing is being done in affiliation with so many cities and mayors around the world … It gives me a sense of working for the common good together with millions of people.”
